CALL USING with WAIT option for copy file1+file3 file4 DOS command

[Kiryl Lamakin <Kiryl_Lamakin/Finance/USHO/SunLife@SUNLIFEOFCANADA.COM>]

SQR 4.3.4
Windows NT 4.0 SP5
MS SQL Server 7.0

I tried to append file2 to file1 and save the result in results_file by using 
the following command:

let $command_str = 'C:\WINNT\system32\cmd.exe /c COPY  c:\file1+c:\file2 
c:\results_file'
CALL SYSTEM USING $command_str #status wait

The problem is that this command doesn't seem working with 'wait' option. At 
the same time it works fine without it. A simple copy of one file to
another works fine
with and without 'wait' option.
